The bottles are adorable and made of heavy glass. I couldn't find the weight marked on the bottle, but I guess around 10mL? Unfortunately I was disappointed in Pink Sprinkles but Purple Sprinkles is okay because it's unique to my stash. I like it best over white, pink and black. It's very thick and dries quickly. Blueberry went on with one thick coat compared to Lapis of Luxury which required three coats to become opaque.
